T o all whom i?? may concern Be it known that we, CHARLES WV. H. BLOOD and CARL GOSTEMAN, citizens of the United States, and residents or" linthrop and Boston, respectively, inl the county of Suffolk and State of Massachusetts, have invented an Improvement in Side Head Construction for Matchers and the like, otwhich the following description, in connection-with the accompanying drawings, is a specification, like characters on the drawings representing likeV parts.

This invention relates to machines having rotary tools directlyl driven by rotary ino'- tors. In its more specific aspects4 itfhas to do with a construction applicable to the side heads of matchers Orlike wood working machines.

Our invention may best be understood' by reference to the Jollowingdescription ot the illustrative embodimenty thereof shown in the accompanying ldrawings wherein we have shown byzwaypotexample as muchf'ot a matcher as is necessary to an understanding ot' our improvements as applied thereto and wherein: Y Y

Fig. 2 is a transverse section ladj'acentthe vside heads;

of the side heads,l the motor casing being omitted; l Y

Fig. 4c is a section on the line l-el-Of Fig. l; and' e Fig. 5 is an endelevation of. one ofr the heads and adjacent mechanism partly in section along the line 5-5 Ot Fig. 3.

.ln the accompanying drawings as an eX- ample of our invention we have shown a matcher wherein they side heads are directly driven by electric motors. In Fig. 1 we illustrate diagrammatically the upper and lower cutter heads 7 and 9 adapted to. act on the upper and lower `faces of a board` passing4 through the machine. From the cutter heads; 7 andY 9' the board passes between the side heads to the feed rolls 11. As best shown in Fig. 2lthe two side heads 13' and15 Fig. 3 is a plan of the mechanism` of one rotate onvertical spindles in apl'anefju'st aboutv theY bed 'not the machine and act simule taneously on Opposite edges of the board j Specification Of Letterrsyatent. r Patqiatigd Mfgav 2, 1922 Application kl'edj-I'uly 7, 1920.

which passes over the supports 16`in contact with the guide 19 and under the holding down device 21'. i

Referring to Fig. 2, the head 13 is mounted on the upwardly projecting rotor 23 of an electric motor 25 mounted beneath the bed ot ythe machine. `Any ordinary or usual adjustments" for positioning the head 13 may be provided but as these adjustments neednot be essentially different in principle orv tornif-romfthe adjustments used with belt driven heads, we have not thoughtl it'necessary to attempt to show or describe them in detail." Y

In a matcher the two heads should be dr'ectly opposite eachother transversely of the machine. The'transverse dimensions of 'the machine arertoo restricted to permit a secondi' motor to be placed side by side withlthe motor 25 while maintaining the alignmento-fthe two heads. `In'acco'rdance with ourinvention we provide Afor driving the cutter head 15 by an electric motor??` which is placed' above the'bed of the machine with the rotor 29 ,thereof depending vertically to'hold the cutter head in operative position above the bed of the machine and Opposite the cutter head `13. A bracket'SO may be provided beneath the cutter head to prevent 'ittroin crashing, to the floor in case of accident,V f

' The arrangement of driving motors for a cutter head' asso far vdescribed we have di's closed and claimed elsewhere. The present invention has more particularly to do with the manner whereby the motor 27 is mounted in its inverted position with provision for Adesired adjustments of the cutter head and insuch a way that the cutter head may be moved away from the bedY of the machine to give access thereto' for changing the saine or -forj'ointing (grinding) it.' Briefly to `summarize the construction shown we provide, as best lshown in Fig@ for Swingin the motor with" the attached cutterk hea about a substantially' horizontal pivot 31 to 'more or less horizontal position, as indicated in dotted linesg'so that the cutter head 15-is vsuspended adjlacent'the'side vof the machine at a distance from the other mechanism and in a position where it may be readilyy removed.' toV permit cutter. hea-ds'V to bel changed or wherein it may be revolved in lcontact with a jointing mechanism.

Referring to the drawings we lhave there shown the entire side head mechanism car ried by a base memberf33 adjustable transversely of the machine on the dovetailed guideway 35, the adjustment being reffected by a screw 37 swivelled in bracket 39 and entering the base plate 33. The base plate 33 carries a standard 41 to which the motor may be secured by means of a motor support 43 having the trunnion stud 31 journalled in the standard 41. By this construction the motor support 43 may be pivoted around a horizontal axis .to bring the parts to* the dotted line positiony in Fig. 1. Suitable stop means in the form of screws 45 and 47 tapping into vlugs 49 and 51 on the motor support 43 and making contact Vwith the motor carrier 67. The support 43 yis pro- -sideof the motor; a f l In the example of -V the invention-here shown they cutter head also has a-vertica1 Y adjustment and for this purpose (see Figs.

standard 41 at the extremes of movement of the' support may be provided. Herein the screw 47 t is provided with a large head in the nature of vva hand wheel permitting relatively slight angular adjustment ofthe m0- tor and its support adjacent theA vertical position thereof. .Y

Forv clamping the motor with the cutter head in its operative-position latch arms may be pivoted to the web '57 connecting the standard 41 to the base plate33 and these arms carry at their opposite ends screws v59 provided with large heads `inithe nature of handwheels which' maybe set up against the. iiange'of the frame member '-6,1rising 35 from `the bed of the machine on the opposite 1 and-.5) the motor support 43 is provided with. a dovetailed .guideway 63 in which slides. the dovetailed rib 65 provided on the vided with a lug 69 receivingthe adjusting screw -71 which taps into a lug 73 on the carrier 67 and thus provides for vertical adjust-v ment of the motorin the dovetailed guide# Away.v 1

torFigs. 3 and 4,f the` member Referring 61 may be provided 4with a Ysuitable abutment surface 7 5 supporting the motor on the side opposite the trunnion bolt 31.

The motor support 43 has'conveniently formed thereonor attached thereto kthe par-l tialv housing vmember 77 (see Figs. 4A andV `5.) which when the motor is swung inwardly vvto operative position mates with the partial housing member 79 onthe member 61 and provides'in cooperation with the member 21 and the ange 81 depending from support 16v anrangular chip hood or flue about'the n cutterhead.k A

.The construction herein disclosed Vis in some respects similar to that'V disclosed in my copending application Serial No. 394,450,

yfiled July 7 1920, and in that application I have'claimed generically certain principles embodied in the constructionshown in the 'Y present application.l This vpresent application is subsidiary to the vone referred to and lherein I. claim only a construction whereinv Y Athe side leg isV mounted for movement about a substantially horizontal axis to bring the cutterhead to an inoperative position. Genl drawings, whatwe claim as new and desire tosecure by Letters Patent we shall express in the. following claims. A

1.v A matcher or like machine comprising the usual horizontal bed, opposed rotary tools operating substantially in the plane of y said bed and rotary motors directlycoupled vthereto and disposed respectively aboveand below the plane, the former having a pivotal mounting on a substantially horizontal axis remote from and above the tool providing an inward position in which the tool is adapted to operate on work passing over the bedand adapted to be swung 'through a'widearcto a vsubstantially horizontal' position. wherein the ftool is distant frornthe bed ofthe ma- ,y

chinel and of convenient access.

2. lA matcher orlike machinecomprising the usual horizontal bed and a side leg which t includes a motorrhaving a dependingrotor` for receiving the cutter vhead to supportthe head adjacent the'bed for operation on work passing thereover, said motor being pivoted on a substantially horizontal, axis remote Vfrom and above said bedrprovidingy for swinging the head through awidearc to an inoperativeposition remote from the bed.v

3. A matcher or like machine', comprising the'usu'al horizontal bed and a side'fleg comprising abaseadjustable transversely of the machine, a standard rising 4therefrom, a

iml

motor support pivoted tothe standard onv a substantially horizontal axis, means for clamping the -supportto hold the motor with Vits rotor dependinglto supportthe side head .in operative position tovact on work passing over said bed, said support being swingable about the pivot on release of -the .clamping meanstocarry thehe'ad to an inoperative position distant from the bed.

`4. A vmatcher or like machine'comprising theusualhorizontal bed and-a side leg'comprising a standard,- amo'tor support pivoted on the standardto swing about a substantially horizontal axis, abutments limiting said movement and providing anfinward'position in which vthemotor is supported withdefV .pending rotor to hold thesidevheadin operative position to act on work passingv over the bed and an outward position wherein.v

the head is swung upwardly through a wide arc to an inoperative position remote from the bed and means cooperating with one of the abutments to effect adjustment of the inward position by relatively slight swinging movement of the support about its pivot.

5. A. matcher or like machine comprising the usual horizontal bed and aside leg including a standard, a motor .support pivoted thereon by means of a horizontal stud at one side of the support, a motor carrier on said support with vprovision for vertical adjustment thereon and adapted to hold a motor with depending rotor to receive a cutter head in operative positionto act on work passing over said bed7 swinging of the support on its pivot providing for lifting the cutter head through a wide arc to an inoperative position remote from said bed and an upright supporting surface engaging the carrier onthe side opposite said stud.

In testimony whereof, we have signed our names to this specification.
